qmice Posted July 9, 2021 Share Posted July 9, 2021 Hi all, thanks for the forum and I had enjoyed the path of hac-mac for long. Below is my config: Gigabyte H55M-UD2H | 32GB-DDR3 | R9-270X | SSD - EVO850 I got a working BigSur OS (installed in the SSD-EVO850) and i unplug it from another machine and I move this OS with the attached EFI. I installed with OC-0.6.6 debug version and rebuild this from scratch. I can successfully boot into OS, (dual-monitor with HDMI and DP ports works) but none of my USB ports can detect of anything. Does anyone can give me a hints / advice what did I do wrong ? What I tried: 1). NVRAM with prev-lang:kbd: en-US:0 2). LegacyEnable: True 3). LegacyOverwrite: True 4). Load with the driver: OpenUsbKbDxe.efi EFI-066.zip Link to comment https://www.insanelymac.com/forum/topic/348215-help-usb-not-working-oc-066-bigsur-h55m-ud2h/ Share on other sites More sharing options...
